Abstract

The most frequent sites of tumors after curative surgery of the thoracic esophagus are in the cervical region and/or mediastinum. Detailed analysis of 187 cases in our hospital showed that postoperative adjuvant therapy, namely, radiochemoimmunotherapy, improved the survival rate of patients undergoing such surgery. This indicates that such therapy prevents the recurrence of micrometastasis after curative surgery. However, the prognosis of patients with positive nodes did not improve, in spite of extensive radical surgery including lymph-adenectomy. In order to improve the prognosis in such cases with positive regional nodes, a newly devised protocol of radiochemocytokine therapy including tumor necrosis factor (TNF), interleukin 2 (IL-2) and a-interferon (α-INF) has recently been performed. For patients with distant node metastasis, conventional postoperative aggressive chemotherapy under active nutritional support has been found to prolong survival. The 5-year survival rate of patients treated with aggressive chemotherapy and radiochemocytokine therapy was analyzed.
